Specification of Letters Patent.

Application filed November 4, 1912. Serial No. 729,437.

To all whom, it may concern:

Be it known that I, HENRY G. DINN, a citizen ,of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Protective Garments, of which the following is a specifi-' Another object of my invention is that the garment will be comfortable and allow the wearer a large scope of vision. v

A still further object of my invention is to render the garment adjustable to fit work men of different sizes and to provide an air circulating means-which will supply fresh air to the workman to be breathed and cause a transparent portion of the garment through which the workman sees, to be kept free from condensed moisture.

Another object is that the garment may be'easily attached or detached and ventilated. Also, that the air supply will be at all times under the control bf the wearer of the garment.

These objects and other-advantages which I will be described hereinafter I attain in the following manner, reference being had to the accompanying drawings in which,

Figure 1, is a side elevation of a garment constructedin accordance with my inven tion; Fig. 2, is a rear elevation of the garment shown in Fig. 1; Fig. 3, is a sectional elevation taken on the line a,a Fig. 2; Fig. 4, is a sectional elevation taken on the line b--b Fig. 1; Fig. 5, is an enlarged sectional elevation of a window which I employ in my garment; Fig. 6, is a detail perspective view showing the window detached from the body of the garment; Fig. 7 is a per spective view of a special form of air distributer which I employ; and Fig. 8, is a detail of a forked-air joint which I preferably use.

Referring to the drawings, 1 is the body of the garment which ispreferably made out of canvas. or other cloth having a head 'piece or hat 2 preferably of leather sewed or otherwise secured thereto. This hat is lined with a felt band or lining 3 or other substance which, when contacting with the head will form a seal in the manner hereinafter more fully described. The hat2 is provided with vent'holes 4t and 5 and the space between the front 6 and the felt 3 forms a socket for the insertion of the upper edge 7 of a window or transparent section 8. The front portion 6 of the hat 2 is provided with snap buttons 9 which are arranged to engage snap buttons 10 on the upper edge 7 of the window 8 when the latter is placed between the felt 3 and front 6 as clearly shown in- Figs. 3 and 5. The body of the garment, below the hat 2 is also provided with snap buttons 11 which are adapted to be engaged by the snap buttons 12 on the flexible frame 8 of the window 8 as clearly shown in Figs. land 3.

At the rear of the garment the felt 3 is split and extended downwardly to a point 13 and an elastic insert 14 'is secured to the inner portion of the garment and is-adapted to overlap the split portion of the felt as is shown in Figs. 2 and 3. A lace or drawstring 15 adapted to engage clasps 16 ar-' range don either side of the split portion of the hat 2 acts as a means whereby the garment may be increased or decreased in size adjacent the hat portion so as to ac.- conmiodate persons of different sizes. ear portion 17 having perforations 17 is provided on each side of the garment'so as to allow the wearer to clearly distinguish sounds and to allow the escape of the air from theinterior of the head section. These ear portions may be made so as to press firmly against-the outer ear. The outer surface of the garment is provided with pivotedarms 18 which may be moved to open the apertures in the ear piece 17, or as shown in Fig.1 ma be allowed to remain closed at the will 0 the wearer. The lower portion of the garment 1 is so out as to provide a forward or front body portion 19 which extends downward from the window 8 and ordinarily ends slightly below the waist of the wearer. The rear portion 20 of the body of the garment has extensions 21 and 22 which extend from the back under the arm of the wearer and are provided with stra s 23 and buckles 24 respectively by which t e arms of the wearer.

ends 21 and 22 may be drawn tightly around the wearer and cause the garment to snugly fit the body. An auxiliary strap 25 is provided on each side of the garment so as to cause the garment to fit snugly around the An air inlet pipe 26 has one end secured to a Y -shaped tube 27 having branches 28 and, 29 and has its other end provided with a couplin 30 having a regulatin valve 31. The Y-s aped tube 27 is secure against the inner'surface of the garment in the presentinstance by. straps 32 and the branches 28 and 29 are fitted within the ends of two pieces of flexible tube 33 and 34 respectively; the latter being supported by cloth bushings 35 and 36 which are secured to the inner-face of the garment. The other ends of the flexible tubes 33 and 34 fit respectively over the ends 37 and 38 of an air distributer 39; the latter having two series of perforations 40 and 41, the series 40 being so arranged as to deflect air upward and toward the inner surface of the window 8, while the perforations 41 distribute the air toward the face and body of the wearer.

When the garment is being worn the head of "the wearer should properly rest against the inner felt 3 and entirely around the circumference of the felt. This will form a seal and prevent any gases from passing below the line of contact of the persons hat with the felt. However, the head will be kept cool by means of the vents or perforations 4 and 5.

In the use of my invention, if a person has to work within a room for examplehaving poisonous gases therein or other matter which would be injurious, a tube'which is attached to an air pump of any description is secured to the-coupling 30. The person may then go in the room and may regulate the amount of air necessary to inhale while in there by operating the valve 31. The force of the incoming fresh air can be made of suflicient strength if necessary to escape through the perforations 17. In this way a fresh supply of air may be always kept 1 within the garment and the poisonous gases or the like prevented from passing into the inhaling space of the arment.

Byhaving the win ow 8 extending to a point below the chin of the wearer a workman is able to see at a wide angle. Also, by having the window attached by means of snap buttons it may be readily detached and attached; the upper portion 7 forming a seal with the hat portion.

By making the inlet tube 33 and 34 branched, the same pass over and conform to the contour of the shoulders of the wearer and insure a proper distribution of the air through the distributer 39.

The window or trans arent section 8 may be made of any suita le substance but I preferably make the same of isinglass or celluloid so as to render the same flexible and permit it being bent to the proper contour so as to fit between the front section 6 of the hat 2 and the felt lining or seal 3. Also, by havin the window 8 made of u flexible materiaflthe workman can admit atmospheric .air without removing the entire window 3. The tubes '26 and 33 can be made of materials having variable degrees of flexibility but should be sufliciently rigid so as not to be flattened when under the pressure of the tightening means of the garment.
